Any progress I've made has been courtesy of my place of employ, which has sponsored Headspace meditation sessions every workday since mid-March, most of which I've attended.
Some days I'm a hopeless case and can barely follow the instructions. But other days I can feel myself in another place, one where thoughts flit into my mind and just as easily float out again; one where following the breath, flowing with the breath, is becoming a little more second nature.
Today, when I heard this line that a happy mind is a spacious mind, a mind that has room for other people, other ideas, I'll admit I broke the first rule of meditation. I didn't let that thought move through and out. I savored it a bit, I pondered the implications.
Equating happiness with spaciousness, yes, it works — though you could just as easily equate it with coziness and smallness and manageability. But in this case I imagined the clear sky that you reach when you soar above the clouds. The spaciousness of the heavens, of the mind unencumbered.
